NCE

The Metasys® Network Control Engine (NCE) Series controllers provide

a cost-effective solution designed for integrating central plants and large built-up air handlers into your existing Metasys networks.

These network control engines combine the network supervisor capabilities and IP network connectivity of a Network Automation Engine

(NAE) with the I/O point connectivity and direct digital control capabilities of a Field Equipment Controller (FEC), making them the ideal choice for expanding and improving your Metasys installation for greater data

visibility and control over your energy usage.

Network Control Engines (NCEs) provide supervisory control of a

specified field bus trunk with up to 32 field controllers. Depending on the model, an NCE supports either a BACnet®

Master-Slave/Token-Passing (MS/TP) trunk, an N2 Bus trunk, or a

LONWORKS® network trunk. Available in Europe only are the MS-NCE2000-0 and MS-NCE2506-0 models, which do not provide a physical field controller trunk connection.

All NCE models feature 33 integral I/O points and a Sensor/Actuator (SA) Bus, which allow you to increase the NCE's I/O field point capacity and also integrate NS Series Network Sensors and Variable Frequency Drives (VFDs) into your NCE application.

Some NCE models feature an integral field controller display screen with a navigation keypad, allowing for easy modifications in the field. In addition, some NCE models feature an internal modem that supports standard dial-up capabilities when traditional IT networks are not available.

Refer to the Network Control Engine Product Bulletin (LIT-12011283) for important product application information.
